KUDOS SK3300H High-Frequency Benchtop Ultrasonic Cleaner

Overview

The KUDOS SK3300H is a high-frequency benchtop ultrasonic cleaner engineered for precision cleaning, degassing, dispersion, emulsification, and accelerated extraction in research laboratories, quality control environments, and small-scale production settings. Operating at a stable 53 kHz frequency, the unit leverages piezoelectric transducer technology to generate controlled cavitation within aqueous or compatible solvent media. This frequency balances penetration depth and micro-cleaning efficacy—offering superior particle removal from intricate geometries (e.g., pipette tips, optical lenses, microfluidic chips, and precision instrumentation parts) without compromising surface integrity. Unlike lower-frequency units (>80 kHz), the 53 kHz output delivers consistent energy distribution across the 6 L tank volume while minimizing localized erosion risk on delicate substrates such as anodized aluminum, thin-film sensors, or coated optics. The device complies with IEC 61000-6-3 (EMC emission standards) and meets general safety requirements per IEC 61010-1 for laboratory electrical equipment.

Key Features

• Digitally controlled timer with adjustable range from 1 to 199 minutes—enabling reproducible process validation for routine QC protocols.
• 180 W nominal ultrasonic power output distributed uniformly across the bottom-mounted transducer array, ensuring homogeneous cavitation field throughout the stainless steel tank.
• 304 stainless steel tank (300 × 150 × 150 mm internal dimensions) with rounded corners and seamless welds for corrosion resistance and ease of decontamination.
• Backlit LCD display providing real-time visibility of set time and operational status under ambient lab lighting conditions.
• Benchtop footprint (330 × 180 × 290 mm) optimized for integration into fume hoods, glove boxes, or shared instrument benches without requiring dedicated floor space.
• Included stainless steel support rack designed to elevate samples above tank bottom sedimentation zone, improving acoustic coupling and cleaning uniformity.

Sample Compatibility & Compliance

The SK3300H supports a broad range of sample types including glassware (vials, cuvettes, chromatography columns), metal components (surgical tools, calibration weights), ceramic substrates, and polymer-based microdevices. It is compatible with water, aqueous detergents (e.g., Alconox®, Liquinox®), and low-viscosity organic solvents (e.g., isopropanol, ethanol) when used within manufacturer-recommended concentration limits and ventilation guidelines. While not certified for sterile processing per ISO 13485 or FDA 21 CFR Part 820, the unit’s design facilitates compliance with GLP documentation practices through traceable timing parameters and repeatable operating conditions. Users performing cleaning validation per ASTM F2792 (Standard Guide for Ultrasonic Cleaning Validation) may employ this model as a stable platform for establishing baseline cavitation intensity profiles using calibrated aluminum foil erosion tests.

Software & Data Management

The SK3300H operates as a standalone analog-digital hybrid system with no embedded firmware update capability or network interface. All operational parameters are entered directly via front-panel membrane keys; no external software or driver installation is required. Timer settings are retained during brief power interruptions (<5 sec), supporting continuity in multi-step cleaning sequences. For regulated environments requiring audit trails, users may integrate the unit into broader lab-wide data capture systems via external programmable logic controllers (PLCs) or time-stamped video logging—though the device itself does not generate electronic records compliant with 21 CFR Part 11. Documentation packages—including user manual, electrical safety certificate, and material declarations—are provided in English upon request.

Applications

• Routine cleaning of HPLC autosampler vials, GC liners, and syringe filters prior to analytical runs.
• Removal of residual photoresist or etch byproducts from semiconductor wafers and MEMS devices during R&D prototyping.
• Preparation of nanoparticle dispersions for DLS or TEM analysis via sonication-assisted deagglomeration.
• Extraction of phytochemicals from plant matrices in natural product screening workflows.
• De-gassing of low-viscosity resins prior to 3D printing or encapsulation procedures.
• Surface preparation of electrodes and biosensors to ensure consistent electrochemical response.

FAQ

Is the SK3300H suitable for cleaning delicate optical components such as microscope slides or laser mirrors?
Yes—its 53 kHz frequency and controllable timing minimize mechanical stress while achieving effective particulate removal. Always use deionized water or low-surfactant solutions and avoid prolonged exposure (>10 min) unless validated for your specific substrate.
Can the unit be operated continuously beyond the maximum timer setting?
No—the timer is a hard-limit safety feature. Manual restart is required after each cycle; continuous unattended operation is not supported.
Does the device include temperature control or heating functionality?
No—the SK3300H is a non-heating ultrasonic cleaner. For thermally assisted cleaning, external water baths or heated tanks must be used separately.
What maintenance is recommended to sustain optimal transducer performance?
Rinse the tank with deionized water after each use; inspect transducer mounting surfaces quarterly for mineral deposits; avoid abrasive cleaners or steel wool on the tank interior.
Is the stainless steel rack adjustable or configurable for irregularly shaped items?
The included rack is fixed-height but features open-grid geometry that accommodates standard labware; custom fixtures can be fabricated using 304 SS wire or PTFE-coated supports compatible with ultrasonic fields.
